Discussion on Some Bionomical Characteristics of Forest Insects in the Tropics

本文论述了热带森林害虫生物学的特殊性!包括世代、寿命、产卵延续期、异常生物学、滞育、休眠、拟态和伪装。经研究发现:热带林虫繁殖快,世代多,象虫寿命和产卵延续期长,球象幼虫别具一格的取食习性,摹拟眼镜蛇的赤顶粉蝶幼虫,用寄主花序伪装的母生花尺蛾幼虫等。

The bionomical characteristics of forest insects in the tropics, such as generations, life-span, lasting period of oviposition, abnormal bionomics, diapause, dormancy, mimicry and pretending have been discussed in this paper. From the results, it was found that the multiplication in generations of the forest insects in the tropics is rapidly. The life-span and the lasting period of oviposition of the snout beetles are even longer and food capture in the larvae of cioninae are of special style. Some larvae like Hebomoia glaubippe L. (Pieridae) imitated the shape as cobra and some larvae like geometrids pretended itself as inflorescence of the host plants.
